Abstract

A system for managing the operation of a plurality of radio modems contained within the same WCD. One or more of the plurality of radio modems may be a dual-mode radio modem enabled to communicate using at least two separate radio protocols concurrently. The operation of the one or more dual-mode modems may be managed by resources encompassed in a radio modem interface coupled to, or integrated within, the dual-mode radio modem. These management resources may receive information from the operating system level of the WCD and from the at least two radio modem stacks utilizing the resources of the dual mode radio modem in order to coordinate the operation of the at least two radio protocols concurrently active in the modem.

Claims

AMENDED CLAIMS (received by the International Bureau on 29 September 2008 (29.09.2008))
1. An apparatus, comprising: a radio modem including a single transceiver configured to support at least two radio protocols, the radio modem including a radio modem interface; and a processor, the processor being configured to: receive operational information for at least one of the at least two radio protocols that share access to the single transceiver, the operational information comprising one or more parameters for controlling operation of the at least one of the at least two radio protocols; receive status information directly from the at least two radio protocols; and create an operational schedule for each of the at least two radio protocols based on the operational information and the status information corresponding to the at least two protocols.
2. The apparatus of claim 1, wherein the apparatus is a wireless communication device including a plurality of radio modems, each radio modem further including a radio modem interface.
3. The apparatus of claim 1, wherein the processor is a Dual Mode (DuMo) manager that is integrated into the radio modem interface, the DuMo manager being configured to coordinate the operation of the at least two protocols.
4. The apparatus of claim 3, wherein the processor further includes an Admission control configured to assign at least radio and connection parameters so that the DuMo manager can coordinate operation for avoiding collisions between the at least two radio protocols.
